ABSTRACT:
A method for preparing glass strand pellets by stirring chopped glass strands in the presence of 10 to 25% of water, the strands being sized with a size containing an organosilane. The method performs stirring for long enough for an increase in density to be at least 67%, the stirring being performed using a single stirring equipment that at each instant imparts to the strands or forming pellets it contains the same stirring frequency, the pellets finally formed containing, after drying, at least 95 wt % glass. A film-forming agent is in contact with the glass strands during the stirring at the latest.
